Hello,
I have to monitor a Cisco Aironet ethernet transfer rate. I can't install Zabbix agent in a AP so SNMP is needed.
I've got a test environment and I can't find the correct MIB variable that I need. There are two variables called IF-MIB::ifInOctects and IF-MIB::ifOutOctets, but their value is the total octects amount, not the transfer rate.
I could use trigger expressions to calculate the transfer rate from ifInOctects and ifOutOctects, but I don't want a trigger, I want a Item so I can draw a graph. :confused:


Thank you for your help!!!!!

Use custom multiplier and Delta (simple change) count method.

What do you mean?
Delta definition is --> max(<period>)-min(<period>).

I still have to divide by the period, but I would define a Trigger with that expression, how can I graph that?

Thank you,

Greetings,

Not quite, instead Delta simply shows what has changed between the last check and the current check.

At present, there is no way to do that. Instead what I would suggest is to check out the Cisco forums and look for the SNMP OID info there. I seem to recall seeing a MIB definition for Cisco that listed total octets, and total octets per time slice. Based on what you describe, you want the total octets per time slice.
